Description

Technical Field

[0001] This utility model relates to the field of downhole fluid supply pipeline maintenance technology, and in particular to an auxiliary device for the maintenance and replacement of pipe clamps in long-distance fluid supply pipelines. Background Technology

[0002] In underground mining operations, long-distance fluid supply pipelines are key infrastructure to ensure continuous production, undertaking important functions such as hydraulic power transmission and cooling medium delivery. When leakage occurs in the underground fluid supply pipeline, the pipe clamps need to be loosened to repair or replace the pipeline.

[0003] When the pipe clamps are loosened, allowing the two adjacent steel pipe sections to be separated, the steel pipes will undergo significant tensile displacement to both sides due to the slope of the well, under the influence of their own gravity and the residual stress of the pipeline system. This results in a large gap between the connectors when installing the steel pipe connectors, and the heavy weight of the steel pipes makes installation extremely difficult, consumes a lot of manpower and resources, and seriously affects maintenance efficiency. Utility Model Content

This results in a large gap between the connectors when installing the steel pipe connectors, and the steel pipe is heavy, making the installation extremely difficult, consuming a lot of manpower and resources, and seriously affecting the maintenance efficiency. Therefore, the proposed auxiliary device for maintenance and replacement of pipe clamps for long-distance liquid supply pipelines is proposed.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0016] Reference Figures 1-3A long-distance liquid supply pipeline clamp maintenance and replacement auxiliary device includes a mounting frame 1. A rotating rod 2 is horizontally rotatably mounted inside the mounting frame 1. The rotating rod 2 has symmetrical threads on its surface. A mounting seat 3 is symmetrically threaded onto the rotating rod 2. A limiting groove 10 is horizontally opened on the bottom wall of the mounting frame 1. A limiting rotating rod 11 is fixedly mounted on the lower surface of the mounting seat 3. The bottom end of the limiting rotating rod 11 is slidably configured in the limiting groove 10. One end of the mounting seat 3 has an installation port 4. Fixed shafts 5 are symmetrically fixedly mounted inside the installation port 4. A clamping hoop 6 is rotatably mounted on the fixed shaft 5. A rectangular opening is opened on one side of the mounting seat 3. A rotating shaft 7 is vertically rotatably mounted inside the rectangular opening. A baffle 8 is fixedly mounted on the rotating shaft 7. The surface of the baffle 8 abuts against the ends of the two fixed shafts 5 and is locked by a locking assembly. The rotating rod 2 is controlled to rotate by a drive assembly. The drive assembly includes a drive motor 17 fixedly mounted on one side of the mounting frame 1. The output shaft of the drive motor 17 passes through the mounting frame 1 and is fixedly connected to the end of the rotating rod 2.

[0017] A mounting block 9 is fixedly installed on the side of the clamping clamp 6 away from the fixed shaft 5. One of the mounting blocks 9 has a limiting component on its surface, which is used to limit the separation of two adjacent mounting blocks 9.

[0018] First, place the two steel pipes into the two clamping hoops 6 located on the same horizontal line. Then, rotate the two clamping hoops 6 located on the upper line so that the two clamping hoops 6 located on the same vertical line come into contact with each other. At this time, multiple mounting blocks 9 will stick together in pairs, forming a ring-shaped wrap around the steel pipes. Then, the two steel pipes are clamped and fixed by restricting the two sticking mounting blocks 9 through the limiting component.

[0019] If the steel pipes have excessive spacing due to stretching, the drive motor 17 controls the rotating rod 2 to rotate in the forward direction. The symmetrical threads on its surface engage with the threads of the mounting base 3, causing the two mounting bases 3 to move closer together under the guidance of the rotation limiting groove 10 and the rotation limiting rod 11. This drives the two sections of steel pipes to move synchronously, reducing the spacing. If it is necessary to disassemble the old connector, the rotating rod 2 is controlled to rotate in the reverse direction, causing the two mounting bases 3 to move further apart, increasing the spacing between the steel pipes and facilitating the removal of the old components.

[0020] Reference Figures 6-8 The locking assembly includes two locking rods 12, and the surface of the baffle 8 has vertical grooves, such as... Figure 11 As shown, locking openings 13 are provided at the top and bottom of the rectangular opening, and through openings corresponding to the positions of the locking openings 13 are provided on the top and bottom walls of the vertical groove. Two locking rods 12 are slidably inserted into the two through openings, with the ends of the two locking rods 12 that are far apart passing through the two locking openings 13 respectively. Pull blocks 14 are fixedly installed on the ends of the two locking rods 12 that are close to each other. Figure 10 As shown, a telescopic spring 15 is sleeved on the locking rod 12, and the two ends of the telescopic spring 15 are fixedly connected to the surface of the pull block 14 and the groove wall of the vertical groove, respectively.

[0021] Hold the pull block 14 with both hands and move it towards the center. At this time, the pull block 14 will drive the two locking rods 12 to slide towards the center along the through-hole in the vertical groove. The telescopic spring 15 will be stretched. When the ends of the two locking rods 12 away from the pull block 14 are completely separated from the locking holes 13 at the top and bottom of the rectangular opening, the locking state of the baffle 8 will be released. Keep the pull block 14 under force and rotate the baffle 8 around the rotating shaft 7 to rotate outward until the baffle 8 is completely separated from the end of the fixed shaft 5, exposing the end of the fixed shaft 5.

[0022] Then slide the old clamping hoop 6 outward along the axial direction of the fixed shaft 5 to disengage it from the fixed shaft 5, thus completing the disassembly of the clamping hoop 6. Follow the same steps to disassemble the clamping hoop 6 on the other side of the mounting base 3. Select a new clamping hoop 6 of suitable size according to the diameter of the steel pipe to be clamped, put it into the fixed shaft 5 and push it axially to the preset position in the mounting opening 4 to ensure that the clamping hoop 6 can rotate flexibly around the fixed shaft 5.

[0023] The baffle 8 is rotated in the opposite direction to reset around the rotating shaft 7, so that its surface is tightly abutted against the ends of the two fixed shafts 5. The pull block 14 is released, and the telescopic spring 15 pushes the pull block 14 to reset under the action of the elastic force, which drives the locking rod 12 to pass through the through hole and insert into the corresponding locking hole 13, thereby realizing the relocking of the baffle 8. At this time, the fixed shaft 5 is restricted in the installation hole 4, and the replacement operation of the new clamping hoop 6 is completed. The replacement of the two clamping hoop 6 can be completed in a short time to adapt to the clamping requirements of steel pipes of different diameters, and improve the adaptability and maintenance efficiency of the device.

[0024] The inner wall of the clamping hoop 6 is bonded with an anti-slip layer 16, which is made of rubber. The rubber anti-slip layer 16 has good elasticity and adhesion, which can increase the friction between the clamping hoop 6 and the contact surface of the steel pipe and improve the fastening effect.

[0025] Reference Figures 4-5 The limiting assembly includes a rotating rod 19, a gear 20 fixedly sleeved on the rotating rod 19, two rack rods 21 both meshing with the gears 20, and two L-shaped limiting rods 22. One of the mounting blocks 9 has a mounting cavity, and one end of the rotating rod 19 is rotatably connected to the cavity wall. Figure 9As shown, the upper and lower walls of the mounting cavity are horizontally provided with sliding grooves 23. A sliding rod 24 is fixedly installed on the surface of the rack rod 21. One end of the two sliding rods 24 is slidably disposed in the two sliding grooves 23 respectively. The left and right walls of the mounting cavity are provided with openings. One end of the two rack rods 21 passes through the two openings respectively and is fixedly connected to the two limiting rods 22 respectively. The rotating rod 19 is controlled to rotate by a transmission component. The transmission component includes a first threaded rod 25 horizontally rotatably installed in the mounting cavity, a slider 26 threadedly sleeved on the first threaded rod 25, and a second threaded rod 27 fixedly connected to the slider 26. One end of the rotating rod 19 is provided with a threaded groove 18. The second threaded rod 27 is threadedly installed in the threaded groove 18. One end of the first threaded rod 25 passes through the mounting block 9 and is fixedly installed with an adjusting wheel.

[0026] In the initial state, the distance between the bottom ends of the two limiting rods 22 is at its maximum value. At this time, the space between the bottom ends of the two rods is greater than the length of the mounting block 9. When the two clamping clamps 6 clamp the steel pipe, the two mounting blocks 9 will abut against each other. At this time, the upper surface of the top of the two limiting rods 22 is at the same level as the lower surface of the mounting block 9 located below. Then, the first threaded rod 25 is rotated, so that the slider 26 threaded on the first threaded rod 25 drives the second threaded rod 27 to move into the threaded groove 18. Since the second threaded rod 27 cannot rotate, under the action of the thread on the surface of the second threaded rod 27 and the groove wall of the threaded groove 18, the rotating rod 19 will drive the gear 20 to rotate. The two rack rods 21 meshing with the gear 20 will drive the two limiting rods 22 to move closer to each other. The upper surface of the bottom end of the two limiting rods 22 will abut against the lower surface of the mounting block 9 located below, thereby achieving the effect of restricting the separation of the two mounting blocks 9.

[0027] When it is necessary to rotate the clamping clamp 6 to separate the two mounting blocks 9, simply rotate the first threaded rod 25, so that the slider 26 drives the second threaded rod 27 to move away from the threaded groove 18, so that the two rack rods 21 drive the two limiting rods 22 away from each other, until the bottom upper surface of the two limiting rods 22 no longer abuts against the lower surface of the mounting block 9 below, and the distance between the bottom ends of the two limiting rods 22 is greater than the length of the mounting block 9. The operation is convenient and quick.

[0028] In this utility model, the device achieves relative movement of the two mounting seats 3 through the symmetrical thread of the rotating rod 2 and the transmission cooperation of the mounting seat 3. This allows for precise adjustment of the spacing between the clamped steel pipes, effectively solving the problem of steel pipe stretching caused by the slope in the well, reducing installation difficulty, and avoiding the inefficiency of manual adjustment. At the same time, the two pairs of clamping hoops 6 can clamp and fix the two steel pipes respectively, ensuring that the steel pipes do not shake during maintenance and guaranteeing operational stability.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
